1Blocker lets you block obtrusive ads, sneaky trackers, and annoying elements on sites. With 1Blocker, you’re safe online and nothing will distract you from enjoying sites. 1Blocker is very easy to use — just flip a couple of switches to start blocking ads and trackers. The app will automatically receive cloud updates to the built-in filters silently, so you don’t need to do anything. It’s as simple as setting and forgetting. 1Blocker is a fully native app designed to extend Safari naturally. It’s lightweight and doesn’t drain your battery by taking up your device’s resources. The blocking itself is super fast because Safari does it itself. We only provide filters to Safari and don’t modify webpages in any way. This vastly improves efficiency because Safari knows in advance what should be blocked. So, with 1Blocker, sites load on average 2-5x faster. It’s important to note that not all ads can be blocked though. Some sites use techniques that make it impossible for us to block their ads using currently available features for Safari content blockers. SECURE BY DESIGN 1Blocker is secure and private. It doesn’t have access to webpages and doesn’t track you in any way. We believe that privacy is not for sale. That's why we don't have an "Acceptable Ads" program. We stay independent, and the only way we make money is through direct sales of 1Blocker in the App Store to you. ADVANCED CUSTOMIZATION 1Blocker is a highly customizable content blocker, providing the possibility to create powerful custom rules. It allows you to create custom rules that block any URL by providing a regular expression or hide any element by CSS. It also lets you block cookies. (Available in Premium) AVAILABLE ON ALL DEVICES 1Blocker is available for iPhone, iPad, and Mac. Your preferences and custom rules are always in sync through iCloud no matter which device you're using. FEATURED IN THE PRESS 1Blocker has been featured in TechCrunch, Lifehacker, MacStories, Macworld, and many more. FEATURES AVAILABLE FOR FREE • The ability to enable one category (for example, Block Ads only) • Whitelisting sites right from the Safari extension • Whitelist synchronization between devices via iCloud FRIENDLY SUPPORT Send your feedback at @1BlockerApp on Twitter or via email. Your feedback is always very welcome and considered for the next release. We have been making 1Blocker since 2015. We believe it’s the best all-around package currently available in the App Store.
